Loading XML Data in the XML COntrol

Controls You Can Use on Web Forms ASP.NET Standard Controls Xml Control

There are three ways to load XML data into the XML Web server control.

Provide a path to an external XML document, using the DocumentSource property.
Load an XML document as an object and pass it to the control, using the Load method in the Page_Load event and assigning the document to the Document property of the XML control.
Include the XML content inline, between the opening and closing tags of the control.

Add an <asp:Xml> control into the Web Forms page. For syntax, see Xml Control Syntax.
Set the DocumentSource property of the control to the path to the XML source document.
The XML document will be written directly to the output stream unless you also specify the TransformSource property. TransformSource must be a valid XSL Transformations document, which will be used to transform the XML document before its contents are written to the output stream. The following example shows how to refer to source documents by using a relative path.
```
<body>
   <h3>XML Example</h3>
   <form runat=server>
      <asp:Xml id="xml1" DocumentSource="MySource.xml"
         TransformSource="MyStyle.xsl" runat="server" />
    </form>
</body>
```

Add an <asp:Xml> control into the Web Forms page. For syntax, see Xml Control Syntax.

Add code to load the XML source document, and assign the source to the Document property of the control. For example:

private void Page_Load ( object src, EventArgs e ) {
    System.Xml.XmlDocument doc = new System.Xml.XmlDocument ( );
    doc.Load ( Server.MapPath ( "MySource.xml" ) );
    System.Xml.Xsl.XslTransform trans = new 
       System.Xml.Xsl.XslTransform ( );
    trans.Load ( Server.MapPath ( "MyStyle.xsl" ) );
    Xml1.Document = doc;
    Xml1.Transform = trans;
}

Private Sub Page_Load ( ByVal src As Object, ByVal e As EventArgs ) Handles MyBase.Load
   Dim doc As System.Xml.XmlDocument = New System.Xml.XmlDocument ( )
   doc.Load ( Server.MapPath ( "MySource.xml" ) )
   Dim trans As System.Xml.Xsl.XslTransform = _
      New System.Xml.Xsl.XslTransform
   trans.Load ( Server.MapPath ( "MyStyle.xsl" ) )
   Xml1.Document = doc
   Xml1.Transform = trans
End Sub

C#

VB

Add an <asp:Xml> control into the Web Forms page. For syntax, see Xml Control Syntax.
Find the <asp:Xml> and </asp:Xml> tags.

Add your XML code between these two tags. For example:

<asp:xml TransformSource="MyStyle.xsl" runat=server>
    <clients>
        <name>Frank Miller</name>
        <name>Judy Lew</name>
    </clients>
</asp:xml>
